Many, if not most network analysis algorithms have been designed specifically for single-relational networks; that is, networks in which all edges are of the same type. For example, edges may either represent “friendship,” “kinship,” or “collaboration,” but not all of them together. In contrast, a multi-relational network is a network with a heterogeneous set of edge labels which can represent ...

Today, communication is main part of everybody’s life. Security is the most important issue in any communication. So we need a secured system to exchange data securely between users. For this purpose of security there are various techniques like cryptography, watermarking and steganography. Steganography is used to transmit information in covered form. In steganography we hide the presence of d...

The difficulty of renumbering a network – i.e., adding and removing an IP prefix due to a provider change or a network merging – is a real issue for most network administrators. It is even considered by a lot of people as a bottleneck issue in adopting Provider Aggregatable addressing for IPv6. In this paper, we propose a set of macros that can be used in configuration files to permit network a...

This work proposes a high-capacity scheme for separable reversible data hiding in encrypted images. At the sender side, the original uncompressed image is encrypted using an encryption key. One or several data hiders use the MSB of some image pixels to hide additional data. Given the encrypted image containing this additional data, with only one of those data hiding keys, the receiver can extra...
